In the precision machining and surface treatment industry, the development process is a key step in realizing fine patterns. However, the developer is highly prone to generating a large amount of foam during circulation, spraying or stirring. Such stubborn foam not only hinders effective contact between the developer and the substrate, causing uneven development and pattern defects, but may also overflow the tank and contaminate the equipment and environment, seriously affecting production continuity and the final product yield.
The market generally faces the problem of foam control: traditional physical defoaming methods have only a short-lived effect, and frequent addition may introduce the risk of impurities; while general-purpose silicone defoamers may have poor compatibility with specific developer systems, affecting the performance of the solution itself or causing surface defects. Finding a professional defoaming product that is efficient, stable and highly compatible is one of the core needs for ensuring the smooth operation of the production line.
In response to this series of pain points, Chemi Tech has developed a series of defoamers specially for developer systems. Our solution is based on a deep understanding of the chemical composition of the developer, and the product has the dual effectiveness of rapid defoaming and lasting foam suppression. Its unique formula ensures stability under high-speed circulation and temperature changes; it can quickly spread over the surface of the foam film, reduce the surface tension, prompt the foam to break, and prevent foam regeneration for a long time.
The specific implementation steps are clear and concise: First, our technical team conducts a preliminary analysis of the customer's specific developer system and process conditions. Then, we recommend a suitable defoamer model and provide a sample for compatibility and effect testing. After the effect is confirmed, we guide the customer to add it to the working tank solution at a very low dosage (usually from a few parts per ten thousand to one part per thousand), which can achieve a significant defoaming and foam-suppressing effect. Daily maintenance is simple; you only need to monitor the foam situation regularly and top up with a tiny amount.
We have served a customer focusing on the manufacture of high-precision circuit boards. Its development line generated a large amount of foam due to high-speed spraying, causing jagged defects at the pattern edges, and the defect rate once climbed. After adopting the developer defoamer customized by Chemi Tech, the foam was effectively controlled within minutes of addition, and the working state of the tank solution returned to stability. After a week of continuous operation, the customer reported that the development uniformity was significantly improved, the pattern defect problem was basically eliminated, the product yield increased by about 15%, and at the same time the number of shutdowns for cleaning caused by foam overflow was reduced, so that the overall production efficiency was effectively improved.
Choosing Chemi Tech means choosing dedication to process details and reliable product performance. Our developer defoamer does not just eliminate foam; it also safeguards your stable production and quality assurance.
